Etiquette
Ideas about refined, proper behavior
Etiquette is the visible layer of culture, the part that people notice most quickly and judge most easily.
Rules about how to eat, greet, dress, or conduct business have always served a social function: they signal membership, signal care for others, and sometimes signal status. Etiquette is not trivial, but it is also not fixed. What is considered refined or proper shifts across time and across communities, and the rules that feel most natural to us are usually the ones we absorbed without noticing.
The trouble with etiquette in cross-cultural encounters is that we tend to feel the violations more sharply than the rules themselves. Something just feels off: a person ate before the host, sat in the wrong chair, wore the wrong thing, or failed to bring something. These moments can create impressions that stick, even when the person meant no disrespect. Understanding etiquette as a learned and locally specific system rather than a universal standard opens up a lot more room for generosity.
